Derrick, In answer to your questions: Q: What are some ways in which our muscles calcify? Stiffen, etc. (ESPECIALLY after workouts) with the build up of lactic acid? A: No one really knows why muscles stiffen after workouts. According to some researchers (see reference below) there are at least 6 possible reasons: 1)lactic acid 2)muscle spasm 3)connective tissue damage 4)muscle damage 5)inflammation 6)spilling of enzymes from damaged cells Cheung K, Hume P, Maxwell L. Delayed onset muscle soreness : treatment strategies and performance factors. Sports Med. 2003;33(2):145-64. namely: Q: What relationship does the type of water we drink play a roll in this and especially what role does the pH of the water we drink have to do with the processes of how our body handles water? A: To my knowledge, the type and pH (within reason) of the water is not of great importance with regard to how it is handled by the body. As you mentioned in your question, our blood pH is about 7.4. The body is very efficient at maintaining this pH because it is essential for survival. For this reason, the effects of very high (raw egg whites, pH 9.0) or very low (lemon juice, pH 2.0) pH liquids are probably going to be restricted to the digestive tract. Q: In combination to all of this, what rolls does carbonic acid play related to our body and the ph of the water in it? A: Carbonic acid is part of the bicarbonate/carbonic acid buffer system that helps maintain our internal pH at ~7.4. Q: What pH should our urine be? A: Urinary pH can vary between about 6 and 7. Q: I just found out recently that distilled water isn't good to drink on a constant basis because of it being really soft and it absorbs minerals in your system and in turn flushes them out. A: Our body is continually taking in and flushing out minerals. The only problem with distilled water is that it has no minerals, so it cannot replace those that have been flushed out. As long as you are eating a good diet and not sweating excessively and or exercising, distilled water is probably fine. However, it would be much better to find a good, clean source of water that does contain minerals including calcium and magnesium. I hope that this helps.
